If you are wondering what Yggdrasil means, it is a very important sacred tree in Norse mythology. That explains the logo and makes it obvious that the company comes from Scandinavia, Sweden to be exact. It was established in 2013 when Frederik Elmqvist started it up after being CEO of NetEnt. Still, developer studio is based in Malta just as is most of European iGaming industry. Yggdrasil has produced a number of good games since 2013, with fantastic visuals and innovative concepts.
Some of Yggdrasil most popular games are of the Vikings trilogy, Vikings Go Wild, Vikings Go Berzerk and the newest Vikings Go To Hell. Typical for Yggdrasil is that their games are played on old fashioned 20 or 25 lines, although there have been some titles recently that build up on that.
